I have a minor problem. At the bottom right of my screen alongside my cable login icon, a flashing blue and white question mark in a circle alternates with a red circle and an oblique line. Every now and then an error box flashes up from it and informs me that I have a critical system error in the form of a "parasite program" and that I should fix it by clicking the baloon for the software (their own of course). If I double click the flashing icon, "Virusburst" malware home site loads up, and runs a trial scan. It then asks me to pay for the program to rid myself of this so called virus.
I'm not sure if the error message is my computer referring to the Virusburster as the parasite program, or Virusburster suggesting that I have a problem that only they can fix.
When this first happened, I went into control panel and removed the program which had installed itself. It remains removed, but the error message wont go away and seems to have made a home for itself permanently. Is there any way I can finally get rid of this nuisance? I have Norton Anti-Virus and Spysweeper which I have run a couple of times, and can find no problem.
